Provided is an anti-galloping device for an electric vehicle. The output end of a rotating speed sensor is connected with the input end of a D/A conversion module. The output end of the D/A conversion module is connected with a comparator input end. The output end of the comparator is connected with the input end of a rotation handle detection module, the input end of a first power pipe detection module and the input end of a second power pipe detection module. The output end of the detection module, the output end of the first power pipe detection module and the output end of the second power pipe detection module are connected with input pins of a singe-chip microcomputer respectively. An output pin of the single-chip microcomputer is connected with the control end of a relay module. The normally-opened contact of the relay module is connected with the input end of a first controller. The normally-closed contact of the relay module is connected with the input end of a second controller. The other end of the contact of the relay module is connected with a speed regulation rotation handle. The output end of the first controller and the output end of the second controller are connected into a motor. The anti-galloping device can achieve the rapid switching of the two controllers for the double-controller electric vehicle when the electric vehicle breaks down.
